John,
Check charging voltage @ alternator post, alternator terminal, terminal on o=
ther end of 1/0 cable, post that terminal connects to. If you can get to the=
conductor in the 1/0 cable, get that too. That should be enough to find the=
problem.=20
Peace,
Pat

Monday a.m. report
fresh charge on battery 40 amp for 30 minutes on saturday trickle charger si=
nce then .. battery voltage 13.4 this a.m. checked with two different meters=
hooked up H.F. 500 amp load tester, voltage reading same as VOM at 13.4
voltage at frame rail terminal also 13.4
battery has 800 CCA capacity
started test... over 15 second test the battery slowly dropped to 320 amps a=
nd voltage read 10.8 (still in the green scale)
stopped test at 15 seconds and two minutes later battery was back up to 12.7=
next step will be check alternator output at battery and terminal point
ok... started truck... engine at 1200 rpm
meter on alternator o/p- voltage is 14.6
meter on battery voltage is 13.5
hmmm...1.1 volt drop in 4' of 1/0 cable....that don't sound right
need to measure resistance of cable I guess...
as an aside... checked voltaged between frame ground and the case of the alt=
ernator... 0.0001 volts
I also took battery back to Wal mart and Quintella checked it... battery is=
good based on her years of
battery experience

When it died, did any of the electrical items still work? Lights, etc.? wh=

I remember the a/c fan still blowing

Donald... How large is the cable from the alternator to the battery? feed=
from battery to alternator is #4 wire
=20
Dave... I was thinking a dirty battery clamp. battery clamps are new this=
year and clean, no corrosion on connections
=20
John... How is the volt meter in your truck grounded, to the frame or to t=
he motor? voltmeter in dash is grounded to dash frame voltmeter used to c=
heck under hood is grounded to frame not engine. I'll go back and check gro=
und connections. Alternator has a ground terminal of it's own... it's #10 wi=
re grounded to the frame and of course the alternator is grounded through it=
's mount.
=20
Pat... what is the relationship between the frame terminal & the rest of th=
e electrical system? Terminal on the frame rail is fed by a 4' piece of #4=
wire from the i/p solenoid lug where the cable from the battery is connecte=
d to the solenoid.
=20
Jimmie.. What's the voltage at the terminal with those accessories 'on' b=
ut the engine 'off' hmmm ?? don't remember checking that, =E2=80=A6 I'll=
do that
How big is the alternator? 100 amp single wire from CVF racing
=20
ya'll have given me lots to check and recheck and some I haven't thought of.=
.. going back through my diagnostics and check connections too. I bought a=
500 amp load tester yesterday and will put sufficient load on the battery. =
Battery is under the cab and I have to lower it to check it out and with th=
e low truck, I have to raise truck on jackstands.. silly me, I thought batte=
ry would be a low maintenance item ...duh. so checking at a shop somewhere=
is a very large pain.
=20
points I'm considering.... larger ground wires from frame to engine.... alte=
